shared-dependency-without-redundancy

The design requires redundant discovery, but this DNS or coordination service, which everything depends on, runs on a single provider or a single replica. Its failure is the whole system's failure.

  • — all of these hold:
  • — the design requirement `availability.discoveryRedundant` is true
  • — any of these hold:
  • — the node's `redundantProviders` is false
  • — the node's `replicated` is false
